Patent EP-0433627-A2 (EP)
Inventor: MUELLER THOMAS DIPL-ING
IPC: B66B1/16
Filed: 1990-11-05
Abstract: The invention is based on a method and apparatus to compensate for load sags of a biased-torque position drive (2) during a starting time period (T1 + T2), having a jerk limiting, acceleration limiting and speed limiting position control (28) with a subordinate speed control (62), which is subordinate to a current control (12). According to the invention, during a first predetermined time interval (T1) of the starting time period (T1 + T2), bias values are additionally supplied to the current controller (12), which bias values are selected as a function of derived position difference values (s), and additionally derived acceleration correction values are supplied as bias values to the current controller (12) during a second predetermined time interval (T2) of the starting time period (T1 + T2). An apparatus is thus obtained for carrying out the method for compensating for load sags and for rapid accelerations during a starting time period (T1 + T2) of a biased torque position drive (2), no analog tacho machines being used and it being possible to keep the cost low. <IMAGE>

Filed: 1990-11-17
Abstract: Es ist ein Ultraschallwandler (1) für die Lithotripsie beschrieben, bei dem piezoelektrische Wandlerelemente (2) an einem Träger (3) befestigt sind und frontseitig mit ersten sowie rückseitig mit zwei Elektroden (4,5) verbunden sind, die an einen elektrischen Impulsgenerator (9) anschließbar sind. Um insbesondere bei fokussierenden Wandlern die Gefahr von Gewebeschädigungen im Fokusumfeld zu vermeiden, sind die Elektroden (4,5) so ausgebildet, daß im frontseitigen Teil der Wandlerelemente (2) ein homogenes Feld und im gegenüberliegenden, rückseitigen Teil der Wandlerelemente (2) ein inhomogenes Feld erzeugt wird. Dadurch wird die Amplitude des neben dem positiven Druckpuls auftretenden negativen Pulses reduziert, welch letzterer für die Gefahr dieser Gewebeschädigungen verantwortlich ist. Um diesen Effekt zu erreichen, ist jedes Wandlerelement (2) mit einer topfförmigen Elektrode (4,5) versehen, die den rückseitigen Teil des Wandlerelementes (2) einschließt. <IMAGE>

Abstract: A compartmented body fluid specimen collection tube (10) is provided which allows the user to select a size compartment (14,16) depending upon the quantity of specimen required. Thus, the tube of the invention may be of the standard size which is much easier for the user to handle than very small tubes when taking a blood sample, but a selected size compartment (14,16) is available. The manufacturer of the tube itself may use a single mold for making tubes accommodating differing required specimen quantities, and, thereafter the vendor may select either size compartment (14,16) for imparting a vacuum and the other processing required into a final product. The invention allows the use of a single standard size laboratory equipment array for processing collected specimens of varying quantities, as well as a single standard stopper (28). Finally, reduced vacuum application or "partial draw" tubes are avoided, thus eliminating the problem of unpredictable specimen draw response because of varying atmospheric pressures at different locations of use.

Abstract: A luminance signal (Y) is applied to a segmentation device (2) and subjects the signal to a segmentation algorithm to produce a region image signal which is encoded in a region image encoder (3). The region image signal is also applied to a region post-processor (4) in which an adapted smooth function is added to the region signal. The resulting modified region image signal is subtracted in subtractor (5) from the luminance signal to produce a texture signal which is encoded by a texture image encoder (6). The encoded signals are conveyed via a data channel (9) to respective region (12) and texture (14) image decoders and the recovered region image signal post-processed in a processor (13) in the same manner as with processor (4). The resulting modified region image signal and the recovered texture image signal are added in an adder (15) to produce a reconstructed luminance signal.

Abstract: A method and apparatus for improving imaging in an X-ray mammography machine having a controllable X-ray source (50) incorporates apparatus for directing the X-ray beam (52) in a preselected configuration onto at least a portion of a target area (60). The creation intensity of the beam is detected (114) in each of a plurality of substantially equal segments (1÷12) of the target area and a first segment of lowest radiation intensity is identified. The X-ray source is adjusted to establish a predetermined radiation intensity in the identified first segment. Second segments are then identified each having a radiation intensity greater than a predetermined percentage of the radiation intensity in the identified first segment. The radiation intensity directed toward the identified second segments is then automatically attenuated by a control system (92, 86) responsive to the radiation intensity detected in the second segments. The attenuation is achieved by moving collimators (58,120,200) into the beam so as to reduce the radiation directed towards the second segments. The beam is scanned over the target and continuously adjusted in accordance with the radiation detected in each of the segments of the beam. In this manner, each area of the target receives just sufficient radiation to provide proper imaging without overexposing area of the target which have less attenuation than other areas.

Abstract: A network (A) carries large image blocks among medical diagnostic equipment (20, 22, 24), archive computer (26), and data handling and display stations (28, 30). Four kilobyte packets of 4 megabyte image blocks are moved from transmit buffers (38) to queuing buffers (42). The order in which packets from the queuing buffers are transmitted on the network medium (10) is determined by a combination of an assigned priority, duration in the buffer, and a statistical availability of the addressed receiving node. A data link (52) at the receiving node includes an elasticity buffer (122) which stores a small plurality of bits, e.g. 5, to accommodate for variances in the clock speed of the transmitting and receiving nodes. A buffer table (60) monitors memory addresses at which preceding data packets corresponding to t he same image are stored and provides address information to send each subsequently received packet. Before transmitting the image data packet, the transmitting node data link first sends a query to the receiving node to check availability to avoid the transmission of relatively large data packets to unavailable nodes. Each transmitting node normally passes a token after it has transmitted one packet of data. When the transmitting node holds the token for several sequential data packet transmissions, it passes a restricted token which allows the other nodes to transmit high priority small messages that are much smaller than the image data packets.

Abstract: In correspondence with the graphic data having a spatial extent, there is the address data table configured of arrays, the dimension of which are not smaller in number than the dimensions of the extent of the graphic data. Coordinate transformation is performed between the graphic data and the address data table, whereby any desired point on each figure can be brought into correspondence with one array number of the address data table. Those memory addresses, of a graphic data table at which the individual graphic data items are sorted, are subsequently stored in the address data table. In case of searching for graphic data located at any desired position, the corresponding array number of the address data table is obtained on the basis of the position, whereupon the desired figure can be searched for through that memory address to the graphic data which is stored. In a case where the memory space of the address data table corresponding to any desired one of cells (each of which is a subspace of a graphic space) is full, relevant information of indirectly utilizing a memory space assigned to another of the cells is substitutionally stored in the address data table, cojointly with the memory address of the graphic data table storing the corresponding graphic data so that the address data table can be used efficiently. When the figure discriminators of the graphic data are stored in the address data, lines or points, the relevant attribute information items, or the like can be extracted selectively and efficiently by deciding the figure discriminators on the searching operation.

Abstract: A token handling device transmits, using an electro-magnetic carrier, data, clock pulses and power to a token. The token transmits data by varying the degree of absorption of the carrier in synchronism with the clock pulses. These data transmissions are detected by a receiver in the token handling device, the sensitivity of which is adjusted each time a token is received. 
     The token could be used in transactions in place of coins, or alternatively could be used for identification purposes in other areas. 
     Data stored by the token could be used to change the way in which the token handling device operates. The token handling device may for example form a vending machine, and the token could be used to alter the pricing of goods vended thereby. 
     The token handling device may be combined with a coin validator, in which case there is preferably a common path from an entrance slot for carrying both the tokens and the coins to appropriate testing apparatus.
